Application am m a, me. miss. mp0s.

To all whom it may concern:

Be it known that I, Josnrn M.-Kmnrrzen, a'citizen of the United States, residin at B gsdale, in the county of Weld and tate of lorado, have invented certain new and useful Im' rovements in Operating-Tables, of which t e following is a specification.

My invention relates to improvements in operating tables for use of surgeons, osteopaths and others in the treatment of diseases, fractures or deformity of parts of the human bod by manual or mechanical operations.

T e primar object of my invention is to produce a tab e which is constructed to provide a wide ran e of adjustments for the proper support 0 a body in the postures best adapted for the treatment of the peculiar disorder for which it is operated upon.-

Another object of my invention residesin providing in connection with the table, a de-' vice whereby a body reclining thereon, may be stretched for the correction of displacement of the vertebrae of the spine or other defective positions of the joints, and in designing the difierent parts of which the table is composed, it has been In purpose to combine cheapness of construction with ease of adjustment and general practicability in use.

I attain the above stated objects by the mechanism illustrated in the accompanying drawings in the various viewsof which like parts are similarly designated, and in which,

Figure 1 represents a side elevation of my improved operating table with its adjustable parts in their normal position, Fig. 2, a similar elevation showing the adjustable parts of the table in one of their'adjusted ositions, in full lines and in other positions m broken lines, Fig. 3, a transverse section taken along the'line 3--3, Fig. 1 drawn to an enlarged scale, Figs. 4'and 5, fragmentary side elevations of the middle portion ofthe table showing two different positions of the middle section of its top, Fig. 6, a plan view of the lower. member of the double foot-end section of the table showing the relative po sition of the stretching device included in my invention, Fig. 7, a plan view of the head-end section of the m le, and Fi 8, a sectioii taken along the hue 8--8, g. 1, looking upwardly in the direction of the arrow drawn across'the line.

My improved table consists of a supportmg structure 2 and a top 3 which is composed of three adjustablesections which in the following description will be referred to as the head-end section 4, the middle or intermediate section 5, and the foot-end section 6.

The supporting, structure consists of two transverse frames each composed of two legs 7 which at their upper ends are connected by 'shar odged cross-bars 8 to which the sections 0 the top are pivotally connected.

The frames are steadied by braces 9 which extend slantingly from the upper ends of their 1e and they are connected by two side mi 9 10 which at the foot-end of the structure are bent downwardly to engage the surface upon which the same is supported and there y increase the stability of the device. The races 9 of the frame at the headend of the table are notched along their upr edges for the support of the correspondmg section of the to hereinafter be more lly described.

The portions of the side railsextending between the two transverse frames are notched in their upper edges to support the middle section of the top 1n its adjusted positions and the rigidity of the supporting structure may be increased b means of two crossieces 12 which at their ends are attache to the side rails adjacent the frames.

"The head-end section of the top which in practice sup rts the head of the patient, is composed o anupholstered l'ea'f which has a central opening 13 to receive the face of; the patient when the nature of the c erati'on" requires him to lie face downwa' on the table, The section is hinged at its rearward end to the cross-bar 8 of the adjacent end so as to be movable either up or downwardly, and it is supported in its adjusted positions by means of a pair of connected pawls or props 14 which are hinged at their upper ends at the under side of the leaf and whlch are sharpened at their opposite extremities to engage the notches of the slanting braces 9 which as hereinbefore described, form part of the frame to which the section is attached. The rops 14 are furthermore connected with tii springslfi which facilitate their adjustment of the table, as will e leaf by' means of coiled.

and aid in maintaining the parts in their ad jrusted positions.

he intermediate section 5 is composed of three upholstered leaves which are joined along their adjacent edges by hinge connections to move in opposite directions. The end leaf of the middle section nearest the head end of the table is pivotally connected by means of hinges to the cross-bar 8 of the frame at its side opposite to that at which the head-end section is attached, and the opposite end-leaf of the section ad acent the foot-end of the table is provided wlth connected supporting pawls or props 16 which are attached thereto by hinges at 1ts under side, and which are sharpened at the1r free extremitiesto support the section in different ositions by engagement wlth the notches in t e upper edges of the side rails of the su porting structure.

y adjustment of the three leaves of the section about their connecting hm es, they ma be positioned in an lar re tion to eac other to provide eit er a convex or concave support for a body reclining on the top of the table, and the relative positions of the leaves may furthermore be varied in, accordance with diiferent requirements by maintaining two of the adjolnlng leaves in their normal alined positions and placing them at an an le to the third leaf as shown in Fig. 4, or y placin all the leaves in angular relation to each ot er as has been indicated in Fig. 5.

. To maintain the leaves of the middle section in their several relative adjusted positions,I have rovided a mechanism which consists of a brace 17 which at one of its ends is pivotally and laterally adjustably mounted on a lug 18 secured at the under surface of the end-leaf of the section to whichtheconnected props 16 are attached, and which.

at its opposite end has a transversestop lil which serves to prevent its longitudinal displacement by en agement with a U-shaped from the op ositeend-leaf of thesection.

The midd e leaf of the section has at its der surface two cleats 21 and 22 of; difi di'ent heights which are placed side by side to engage the bracein two of its adjusted ositions.

,The race 17 extends between the downwardly extending members of the hanger so that its transverse sto may engage with either. One of the said members has in its inner edge, two notches 23 and 24 to provide seats at difierent distances from the under surface of the leaf to receive the end of the brace, and the other member has oposite to the lower one of said seats, a simi- Far notch 25 which is provided for the same purpose. I

When the leaves of the middle section are in their normal alined position as shown in anger 20 whic is pivotally suspended" Fig. 1 of the drawings, the brace resting in the upper notch 23 engages the lower surfaces of "the three leaves and thereby supports them against downward deflection.

- When the leaves are adjusted to provide an archedsupport for the body, as is illustrated in Fig. 2, the brace is moved laterally to engage the lowest cleat 22 and is supported in the notch 25 of the hanger, the engagement of its cross piece 19 with the member of the hanger in which the said notch is formed, holding it against longi- .tudinal displacement.

When the leaves are deflected to provide a hollow or concave support for the body, they may be placed in either of the two positions shown in Figs. 4 and 5. In one of these Positions (that illustrated in Fig. 4) two 0 the leaves are placed in alinement at an angle to the third leaf, and the brace 17 which engages the lower surfaces of the alined parts, rests in the notch 24 of the ban er. In the other adjustment of the mid e section of the table, the three leaves extend in angular relation to each other as shown in Fig. 5, and the brace laced in engagement with the lower obllque surface of the cleat 21, rests upon. the cr0ss-piece at the lower end of the hanger.

The foot-end section of the table top consists of two members 26 and 27 which at one of their ends are movably connected by means of hinges 28, and one of which rests nor-mall upon the other, as shown in-Fig. 1.

The ower section consists of a frame which as best shown in Fig. 6, is composed of 'de and cross-bars and wh1ch at its end adjacent the middle section is joined to the cross-bar 8 of the adjacent frame of the supporting structure by hinge-connections which permit of its being moved either up or downwardly.

The upper member 27 of the foot-end section consists of an upholstered leaf which may be held inany ofa number of predetermined angular positions with relation to the lower member by means of a jointed prop 29, the hinged parts of which are yieldingly held in alinement by means of springs 30 which permit of their being placed in an lar relation to each other, as is shown in ig. 2.

The prop as shown in the drawings is composed of three parts and consequently is adapted to hold the upper member of the section at three different angles with relation to the lower section of the same.

The foot-end section is in its entirety supported at its end opposite to that at which it is attached to the cross-bar 8, upon connected, jointed uprights 31 which at their lower ends are pivotally mounted between the ends of the side rails of the supporting structure.

The uprights are composed or two parts which are joined by hin e connections as at 32 and normally maintained in alinement by means of springs 33 which are adapted to permit the up or arts of the uprights to be folded upon t eir ower ones, for the purpose of supporting the section in a downwardly slanting osition as is indicated in Fig. 2 in broken ines.

rom the above descrlption it will be seen that my improved table may be readily adjusted to an position required for the comfort and re ief of the patient, or to facilitate manipulation or operation upon affected parts of the body, by placing them i within easy reach of the operator.

\Vhile the precise form of the sections of which the table top is composed is not ma terial in adapting them for the principal purposes for which they are provided, I

preferab1y make the foot-end section of greater width than the head-end section and taper the intermediate section to correspond at its ends with the outer sections, as is shown in Fig. 8 of the drawings.

The stretching device which is a plied to the table for the purpose of exten ing a body reclining thereon, consists of a U- shaped metal frame 34 which is slidingly mounted in bearings 35 between the side bars of the lower member 26 of the foot-end section.

The cross-bar of the frame which extends beyond the foot-end of the table has two depressions 36 adapted to receive, in practice, the ankles of a patient reclining on the table. The depressions are preferably padded to prevent possible injury, and suitable straps 37 are provided to secure the legs of the patient to the cross-piece, as is required in the stretching operation.

A rock shaft 38 mounted in bearings on the part 26 of the foot-end section, has a pair of parallel arms 39 which by means of rods 4.0 are operatively connected with the adjacent extremities of the side members of the U-shaped frame, and an arm 41 formed at an extremity of the shaft in angular relation to the other arms, is by means of a rod 42 connected with a treadle 44' which is pivotally mounted on the adjacent side rail of the. supporting structure.

A- rack bar 43 secured to the leg of the table past which the treadle extends, serves to secure the latter in its adjusted positions.

In the use of the stretching appliance, the upper portion of the patients body is by means of a suitable harness, secured at the head end of the table which to this end has been provided with fastening devices such as the hooks 46 shown in the drawings.

The legs of the patient which engage the padded portions of the crdss-piece of the sliding frame 34, are secured thereto by the beforvmentioned straps 37, and the body is stretched to any desired degree by downward pressure on the treadle which through the instrumentality of the rock shaft, causes the frame-to which the legs of the patient are attached to slide outwardly.

The harness which secures the u per portion of the body may be of any suitable design to secure the head, shoulders or arms of the patient, and inasmuch as its exact design or construction does not form part of the present invention, only its ends at which it is attached to the table have been shown in the drawings at 45.

It will be understood that by moving the support 31 about its pivots by which it is connected to the side rails 2, the foot-end section of the table can be let down to the floor and that modifications in the arrangement and construction of the parts of my improved table may be resorted to within the scope of my invention as set forth in the following claims.
